Problems solved by technology

In addition to fragments, the detonation or mechanical fragmentation of the projectile or explosive head in or close to the target results in incendiary compound particles which fly at high speed and burn autonomously in the air.
This results in a three-dimensional incendiary effect which extends over a long time.
The metal additive itself results in an increase in the blast effect and in lengthening of the flame life from 1 ms to 15 ms.
This increases the probability of ignition of combustible material.

Embodiment Construction

With reference to a projectile as described in DE 10 2005 039 901 A1, this projectile may be adapted for use as a projectile in accordance with the present invention, wherein the adapted projectile has submunitions 1 which have a hard-metal body and / or heavy-metal body 2, with a bore or recess 5, for holding an energetic component 3. An igniter 4 preferably ends flat with the housing body 2.

The energetic component 3 may be a powder, a rod material, or the like.

In a first non-limiting embodiment of the invention, the zirconium powder is precompressed in the projectile bore 5, and the igniter 4 is metered and is compressed to about 400 MPa. The ratio used for this purpose may, in this case, be 10 / 1.

In a further non-limiting embodiment of the invention, pyrofuze is cut into parts with a length of 8 mm, and is inserted into the projectile bore 5. In this case as well, the igniter 4 is metered and compressed. A ratio of 10 / 1 is also sufficient in this case, and it is been found to be adv...

Abstract

The invention relates to a subprojectile (1) comprising a body, which is provided with a borehole (5) and consists of hard metal or heavy metal, an energy component (3) with or without a firing means (4) being incorporated into the borehole (5). The energy component (3) with or without a pressure-sensitive firing means (4) is fired or activated by air friction, by an ignition in the carrier bullet together with a firing charge, or at the latest when the target is hit.

Description

FIELD OF THE INVENTIONThe invention relates in particular to spin-stabilized submunitions of a projectile which have an energetic content.BACKGROUND OF THE INVENTIONIt is known for incendiary compounds to be included as a fragmentation incendiary munition in a projectile body or explosive head together with a high explosive and in armour-piercing projectiles which do not contain any explosive. In addition to fragments, the detonation or mechanical fragmentation of the projectile or explosive head in or close to the target results in incendiary compound particles which fly at high speed and burn autonomously in the air. This results in a three-dimensional incendiary effect which extends over a long time.Known fragmentation incendiary munitions contain mixtures of high explosives such as hexagon, octagon trotyl and aluminum powder.DE 29 01 517 describes an incendiary compound having an organic binder and metal foam, for example composed of zirconium or hafnium, with polytetrafluorethy...
